  • Publication number: 20120121536
    Abstract: Glucose deprivation is an attractive strategy in cancer research and treatment. Cancer cells upregulate glucose uptake and metabolism for maintaining accelerated growth and proliferation rates. Specifically blocking these processes is likely to provide new insights to the role of glucose transport and metabolism in tumorigenesis, as well as in apoptosis. As solid tumors outgrow the surrounding vasculature, they encounter microenvironments with a limited supply of nutrients leading to a glucose deprived environment in some regions of the tumor. Cancer cells living in the glucose deprived environment undergo changes to prevent glucose deprivation-induced apoptosis. Knowing how cancer cells evade apoptosis induction is also likely to yield valuable information and knowledge of how to overcome the resistance to apoptosis induction in cancer cells.

    Abstract: Special extracts of grape berries and Goji berries can be prepared by exposing fruit juices or preparations to an insoluble binding resin which is then extracted with soluble polyvinylpyrollidone. Grape and Goji extracts made in this way can be used to inhibit or control platelet aggregation. Grape extract has exceptional antibacterial properties and can be used to control oral bacteria and to control MRSA (Methicillin-resistant Staphylococcus aureus). The combination of control of platelet aggregation and antibacterial properties exhibited by the grape-extract allows it to be used to significantly extend the life of isolated platelets. When added to solutions of isolated platelets, the grape extract prevents bacterial growth and prevents deterioration of the platelets through activation. This treatment extends the usable life of platelet concentrates to at least ten days. In addition, polyphenols can be used as a medicament for modulation of platelet activity in vitro.

  • Patent number: 7126031
    Abstract: New ligands and compositions with bridged bis-aromatic ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylene.

  • Patent number: 7045664
    Abstract: In a process for producing bisphenol A, an adduct of bisphenol A with phenol is promptly recovered in highly purity and high efficiency from a reaction mother liquor in the case of singling out bisphenol A from a reaction product. An adduct layer of bisphenol A with phenol is formed by crystallizing an adduct of bisphenol A with phenol from a solution of bisphenol A in phenol to form a slurry, the bisphenol A being produced by reacting phenol and acetone in the presence of an acid catalyst, subjecting the resultant slurry to a solid-liquid separation treatment, and thereafter removing the phenol from solid components, characterized by pouring onto a filter, a slurry solution of bisphenol A in phenol, the slurry solution containing in a crystalline state, an adduct of bisphenol A having an average particle size in the range of 0.05 to 1 mm with phenol, and filtering the slurry solution under reduced pressure in an atmosphere of an inert gas stream at 30 to 80° C.

  • Patent number: 7019179
    Abstract: A process produces an aromatic compound by bringing an aromatic compound (B) into contact with molecular oxygen (C) in the presence of a catalyst (A) comprising at least one of (A1) a heteropolyacid and/or a salt thereof, and (A2) a mixture of oxoacids and/or salts thereof containing, as a whole, one of P and Si and at least one selected from V, Mo and W to thereby yield another aromatic compound (G) than the aromatic compound (B). The process can produce, for example, a corresponding aromatic hydroxy compound (G1) by allowing the aromatic compound (B) to react with the molecular oxygen (C) further in the presence of a reducing agent (D).

  • Patent number: 6960641
    Abstract: A method of preparing block copolymers by solid state polymerization is described. A mixture of a partially crystalline polycarbonate having activated terminal aryloxy groups, for example terminal methyl salicyl groups, when heated together with an oligomeric polyester having reactive terminal hydroxy groups under solid state polymerization conditions affords block copolymers. The activated terminal aryloxy groups play a key role in preserving the block lengths of the starting materials. A control sample in which the partially crystalline polycarbonate lacks activated terminal aryloxy groups, for example polycarbonates substituted by phenol, affords a much lower molecular weight, more highly randomized copolymer product. The product block copolymers are useful as “weatherable” plastic materials.
